THE CHALDEAN LITURGY (in Aramaic) underwent a reform last year and Zenit has an article on it.

Praying in Jesus' Own Language

Interview With Professor of Chaldean Liturgy

VATICAN CITY, JAN. 22, 2006 (Zenit.org).- The Chaldean Church, whose patriarch resides in Baghdad, Iraq, takes pride in its ancient liturgy which uses the same language Jesus used.

In November, the Chaldean liturgy underwent a reform following a special synod in Rome.

To assess the extent of the reform, ZENIT interviewed Monsignor Petrus Yousif, professor of Syro-Chaldean patrology and Chaldean liturgy at the Pontifical Oriental Institute and the Catholic Institute of Paris. He is also the parish priest of France's Chaldean community.

In this interview, Monsignor Yousif, consultor of the Special Liturgy Commission for the Oriental Churches, shares his insight into the Chaldean rite, which uses Aramaic.

I have to say that I doubt that the Aramaic of the liturgy is really "pronounced as Jesus pronounced it," i.e., in first-century Galilean Aramaic. But it's true that it's a dialect of the same language.
